Do enough research to make this post.
.
I asked a lot of people who the author was.
.
No one answered me 😒
.
But ... I found the answer by googling, as many things are found in these times.
.
I also googled who Chen Si is and found out that he is a Chinese man who has prevented more than 300 people from committing suicide on the Nanjing Yangtze River Bridge in Nanjing, China.
.
Then I googled Kintsugi and learned that it is a technique of Japanese origin to fix cracks in ceramic with resin varnish dusted or mixed with gold, silver or platinum dust.
.
Well after the suspense I tell you that the author is @untalrraa as well as the last 6 photos.
.
Do you know why I couldn't find whose mural this was?
Because he does not sign them !!!!
